    Abstract: A system and method are provided for imaging in scattering media such as fog, water and biological tissues. Normally, such images suffer from poor visibility due to backscattering and signal attenuation. At least two images are taken of the scene using active widefield polarized illumination, with different states of a camera-mounted polarizer. The degree of polarization of backscatter is estimated in every point of the scene, leading to an estimation of the backscatter in every point of the scene. A portion or all of the value of backscatter can be deducted in each point of the scene resulting in an enhanced image with improved contrast and brightness range across the field of view.

    Abstract: A self-propelled device for locomotion through a lumen, comprising a set of serially arranged inflatable chambers, and incorporating a number of novel aspects. To enable easy insertion and use, the rigidity of the device is increased by means of rigid inserts in the balloons, or by use of stiff springs between segments. The working channel can be attached to the distal chamber of the device, such that it is pulled from the leading end of the device during inflation, rather than being pulled from the trailing end of the device during deflation. Lumen wall inspection or treatment facilities are enabled by means of a camera or treatment arm mounted between two distally positioned balloons, the device is able to provide observation capabilities to the lumen wall, yet without becoming excessively dirty by exposure to the front end of the device, as in prior art camera units.
